This study was undertaken to quantify the naturally occurring arsenic in the groundwater and chemical body burden caused by its ingestion at some villages of Fatehabad district, Haryana, India. The arsenic levels in groundwater were quantified by hydride generation atomic absorption spectrometry (HG-AAS). Arsenic concentration in the groundwater was found to be in the range of <0.05 to 4.53 µg L−1 which is within WHO and BIS acceptable limits (10 µg L−1). The significant positive correlation between pH - As (r=0.38**; P<0.01) showed that arsenic is more soluble in water at higher pH values. Oral arsenic exposure via groundwater ingestion ranged from <0.003 to 0.31 µg kg−1 day−1 which is significantly lower than WHO and BIS acceptable level (0.68 µg kg−1 day−1). The calculated non-cancer health risk was <1.0 which indicated that chemical burden caused by arsenic through drinking water in the study area is not a cause of concern. The calculated carcinogenic health risk was in the range of <5.06E-06 - 4.59E-04 which is slightly higher than acceptable limits.

印度哈里亚纳邦西南部地下水中砷的评估及其摄入引起的化学身体负担

本研究旨在量化地下水中天然存在的砷以及印度哈里亚纳邦 Fatehabad 地区一些村庄因摄入砷而造成的身体化学负担。地下水中的砷含量通过氢化物发生原子吸收光谱法 (HG-AAS) 进行量化。发现地下水中的砷浓度在 <0.05 至 4.53 µg L-1 的范围内，这在 WHO 和 BIS 可接受的限度内（10 µg L-1）。pH - As 之间的显着正相关 (r=0.38**; P<0.01) 表明砷在较高的 pH 值下更易溶于水。通过地下水摄入的口服砷暴露范围为 <0.003 到 0.31 µg kg-1 day-1，显着低于 WHO 和 BIS 可接受的水平（0.68 µg kg-1 day-1）。计算出的非癌症健康风险 <1。0 表明研究区饮用水中砷引起的化学负荷不值得关注。计算出的致癌健康风险在 <5.06E-06 - 4.59E-04 的范围内，略高于可接受的限度。
